Rivieraman Posted December 30, 2009 Share Posted December 30, 2009 Tony there was a guy in CA that can rebuild those for 400.00 i found a pump on a 90 Riviera that will work. 1988-1990 Riviera, Reatta are the same. the ABS pump off a 1988-1990 Eldo Siville will work too. When i priced the unit at the Buick dealer it was about 3000.00 (yickes). Hope this helps but i went thought the same thing my Riviera had 70,000 miles got it fixed and the ASB light went off and it works great Link to comment Share on other sites More sharing options...
Guest jcc3inc Posted January 9, 2010 Share Posted January 9, 2010 Sir,Is the master cyl a Teves system? Is there a spherical accumulator on top? If so, go to the Reatta forum; it is a very active group and the Teves system is on all Reattas until 1991.Regards,Jack C. Link to comment Share on other sites More sharing options...
Barney Eaton Posted January 9, 2010 Share Posted January 9, 2010 Try SIA in Tilden Ill, 800-737-0915They have rebuilt pump units for $305 and they might be willing to sell you replacement parts. Link to comment Share on other sites More sharing options...
